Southwest Gas Holdings, Inc. files its annual report describing a streamlined business now focused solely on its regulated Natural Gas Distribution segment after deconsolidating Centuri in August 2025. Through Southwest Gas, it serves about 2.28 million customers across Arizona, Nevada, and California, with 2025 operating margin concentrated in residential and small commercial users at 85%, and transportation contributing 11%.
The report highlights heavy reliance on state regulators for rate-setting, widespread use of decoupling mechanisms to stabilize margin, and planned growth investments, including the Great Basin 2028 expansion project. It notes macro risks such as inflation, higher interest rates, competition from electrification, climate-related policy shifts, and cybersecurity threats.
Financially, the company reports an aggregate non‑affiliate equity market value of about $5.35 billion and 72.27 million common shares outstanding. A key disclosure is a material weakness in internal control over financial reporting tied to state tax apportionment, which required restating certain 2025 interim periods and could affect future reporting if remediation is not effective.
